22 Claims.

This invention relates to the hatch construction of a metal car roof. It has for its principal objects to produce a strong, durable, simple and economical hatch construction and to attain other advantages hereinafter appearing. The invention consists in the hatch construction and in the .combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawings, which form part of this specication and wherein like sym-` bols refer to like parts wherever they occur,

Referring to the accompanying drawings, my invention' is shown in connection with a refrigerator cai-,roof comprising end and intermediate metal roof sheets I and 2, respectively, that extend from side plate 3 to side plate 3 of the car and with their ends resting on and riveted or otherwise 'rigidly secured to the sloping top anges of eaves angles 4 whose vertical anges are riveted or otherwise rigidly secured to upstanding inner side marginal flanges 3a of said side plates. The roof sheets are provided along their adjacent margins with upstanding lianges 5 that are straddled by seam caps 6 that are riveted to said flanges and to the top anges of the eaves angles 4. At the end of the car, the end roof sheet I is supported on and riveted or otherwise rigidly secured to the outstanding top flange' of an end angle 'I, whose vertical ilange is riveted or otherwise rigidly secured to the upstanding ange 8a of-an end plate 8.

The end roof sheet I is provided with one or two` hatchways for admitting ice to theA interior (Cl. 10S-5) of said car. The hatch openings are provided with rigid metal frames 9 that are secured to upstanding anges I provided therefor on the end or hatch sheet along the margins of said openings. Each of these metal hatch frames may be made in the form of a casting, or of four frame members welded or otherwise rigidly secured together at the corners of the frame, or of two members bent in the form of U-shaped half sections with their ends disposed in abutting relation and welded or otherwise rigidly secured to gether.

The metal hatch frames are supported on spacedparallel carline members I2 that extend from side platey 3 to side plate 3 and are rigidly secured thereto. The metal hatch frames span from carline to carline and are rigidly connected thereto and thus form the cross-members of a carline unit or assembly that can be assembled CIT the car and furnished for application to the car as a complete, preassembled unitary structure. As shownin Figs..1 to 6, inclusive, the carline members I2 are metal bars preferably of oblique-angle section arranged with their sides converging downwardly and provided at their ends with angle brackets I3 having one flange secured to the side of a carline member and the other flange secured to a side plate.

Each of the metal hatch frames shown in Figs.

, 1 to 4,*inclusive, comprises a relatively wide upper portion I4 located above the general level of the roof, a relatively narrow lower portion I5, located between and resting flatwise against the opposing side faces of the spaced carline members I2 and a shoulder I6 that rests flatwise upon the tops of said carline members.. The wide upper portion I4 of the metal hatch frame has upwardly converging side walls that terminate at the top of said frame in an inwardly extending ilange I'I that constitutes a seat for a hatch cover I8 that is hinged, as at I9, to one of said walls; the narrow lower portion I vof said frame has downwardly converging side walls that conform to the downwardly converging sides of the carline members I2 and serve as a seat for a hatch plug 2U; and the web, which connects the side walls of the upper and lower portions of said frame and forms the shoulder I6, is inclined inwardly and downwardly to conform to the inwardly and downwardly inclined tops of said carline members. The hatch frame is rigidly secured to the carline members preferably by Welds to opposite sides thereof,

against the upwardly converging side walls of the wide upper portion I4 of the hatch frame.

In the mcdiedhatch construction shown in Fig. 5, the wide upper portion of the hatch frame is of uniform width from top to bottom and has vertical plates 23 welded therein that serve as strengthening and stiffening webs therefor, the inclined shoulder and the upper flanges of the carline members have a comparatively steep slope, and the top flanges of said carlines are extended," outwardly beyond the hatch frame to form supports 24 for the hatch sheet.

In the modified hatch construction shown in Fig. 6, the hatch frame is made in the form of a casting whose Wide upper portion has integral stiifening webs 25 and is provided near the upper end of the inclined shoulder with an outstanding flange 26 that forms a continuous support for the hatch sheet around the hatch opening therein. In this construction, the shoulder and the flange 26 of the hatch frame are supported on the tops of wooden carlines 21, whose opposing faces converge downwardly to conform to the downwardly converging sides of the lower portion of said frame.

In the modification illustrated in Fig. 7, the carline members have horizontal top` flanges 29, thereby limiting the contact between the hatch frame and said carline members to the downwardly converging portions thereof; and the ange, which surrounds the opening in the hatch sheet, is secured by rivets 28 to the side walls of the wide upper portion of said frame.

The hatch construction hereinbefore described has numerous advantages. The shape of the hatch frame permits it to rest on and be supported directly by the carline members; and it also permits easy removal and replacement of the hatch sheet without disturbing the hatch frame, as the upwardly converging side walls of the hatch frame provide ample clearance between the opening in the hatch' sheet and the upper end of the hatch frame. The resiliency of the ange around the hatch opening in the roof sheet serves to maintain said flange in contact with the hatch frame while it is being welded thereto and thus prevents the welding material or sparks from getting below the roof sheet and igniting the insulation; and it also permits said flange to yield slightly and accommodate itself to slight misalinement of the hatch frame and the opening in the hatch sheet and stili remain in contact with the hatch frame. The resilient engagement of said flange with the upwardly converging upper side walls of the hatch frame also serves to support the roof sheet in the region of said opening. The web, which connects ,the upwardly converging upper side walls of the hatch frame with the downwardly converging lower side walls thereof, serves to stiffen the section against deflection and to provide a rigid abutment for receiving the shock of ice striking thereagainst. l

Welding of the hatch frames to the two carline members forms a strong and rigid carline assembly that can be assembled off the car and furnished for application to the car as a complete preassembled unit.
